SPEED-CONTROLLED MECHANISM.

Application filed May 15, 1915.

To all whom it may concern Be it known that I, JEAN F. WEBB, Jr., residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in SpeecLConti-olled Mechanism, of which the following is a specification.

My invention relates to the art of train stopping and controlling and it specially has relation to that type of mechanism disclosed in my application filed August 22, 1914, Serial No. 858,094, and that disclosed in the application filed by Jean F. Webb, S12, and myself October 12, 1914:, Serial No. 866,356. The train stopping mechanisms of those applications include means whereby the engineer may reset the operative parts, subject, however, to the action of a speed control that is designed to prohibit such resetting when the train is moving above a predetermined minimum speed.

lhe present invention relates particularly -to the governor for the resetting device and the mechanism for driving the governor from a moving part of the train.

The governor proper herein disclosed, which is also disclosed in my Patent #1,125, l19 of Jan. 19, 1915, but, per se, is not the invention covered by such patent, consists generally of a rotatable shaft on which a sleeve is provided that is raised and lowered by a centrifugal ball device, a weighted latch being operated by the eleva tion of the sleeve to engage the notch in the resetting rod when the speed of the train is above a predetermined minimum to hold the rod from movement.

The mechanism by which the governor shaft is driven and which forms one of the essential features of this application, comprises a gear set having a drive connection with the governor spindle and mounted in a box on the governor case or housing, the governor gear set including a driving element that is coupled up with the driving wheel gear set that is in turn carried by a movable support on which the friction drive wheel is also carried.

More subordinately the invention comprises a friction drive wheel having pro- Specification of Letters latent.

vision to permit it to ratchet, or run free, as it were, in the event of the engine drive wheel racing as frequently occurs When a train is started up.

Again, the invention comprises a combined governor and speedometer drive whereby the speed at, which the governor actsmay be indicated.

Again, it is the object of the invention to provide a governor drive which is so constructed that it can be manufactured at low cost, and in which the parts are designed to occupy a small space only and not interfere with the machinery of the ordinary locomotive to which it is adapted to be attached.

The invention also includes those novel constructions, combinations and arrangements of parts, which will hereinafter be fully described and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which:

Figure l is a side elevation showing the invention in use. Fig. 2 is an enlarged elevation of the present invention, he cover of the governor housing being removed. Fig. 3 is a vertical section on the line 3-3 of Fig. 2. Fig. 1 is side elevation and part section on the line 1 l on Fig. 5. Fig. 5 is a plan view and part section on the line 55 of Fig. l. Fig. 6 is a detail section on the line 66 of Fig. 5. Fig. 7 is a plan view of the lower half of the governor gear box with the gears in place. 8 is a cross section on the line 88 of Fig. 2. Fig. 9 is a vertical section on the line 9-9 of Fig. 10. Fig. 10 is a horizontal section on the line 1010 of Fig. 9.

In the drawings, in which like letters of reference indicate like parts in all of the figures, 13 designates the resetting shaft of the train stopping apparatus by which the engineer may reset the apparatus. Mounted upon suitable brackets 77 at a suitable location on the locomotive is the governor box or housing 78, which is open at the front and back and designed to be closed by cover plates 7 9. The housing 78 is vertically bored at 80 at the top and bottom to receive the lug 109 of the gear set at the bottom and a closure plug at the top, al-

though it should be stated that these parts may be reversed in practice, where conditions make it. necessary.

' 8ldesignates ball races which contain the 'bearingballs 82 to form a bearing between the housing 78 and the flanged collars 83 that are pinned at 84 to the governor shaft 85. The shaft 85 has key lugs 86 by means of which connection can be made with the drivenv shaft 1100f thegovernor gear set.

' Slidably mounted on the shaft 85 is a sleeve 'welghted latch 96 is movable up and down 87 having a slot 88 through which the pin 89 passes, the pin 89 also passing through the shaft 85 and through the ears 90 of the governor balls 91, the ears 92 of which are linked at 93 to thelugs 94 of the sleeve 87.

9 5 designates guide rods that are mounted in the governor housing 78 and on which the to bring its lug 97 into the-notch 102 of the V resetting rod 13 when the speed of the train is above the predetermined minimum. The weighted latch member 96 is made in two vertical halves which are secured together by screws 101 or in any other suitable way, whereby should one lug 97 break or become injured, the device can be turned around 180 and the other lug 97, (see Fig. 3) can be brought into operative position.-

98 design'atesball race members having bearing balls 99 to aflord a ball bearing connection between the sleeve 87 andlatch 96, the ball bearing resting upon the flange 100 V of the sleeve 87.

The governor gear box is composed of an upper and a lower half section 103104,

, separated upon a central horizontal plane and secured together by cap screws 106, four bling the same.

105 designates lugs on the gear case through which the bolts 106 pass.

The case sections 103104 are provided with bearings 109108 respectively for the shaft 110 that has a slotted end .to receive the lug 86 and make connection withthe governor 85, as best shown in Fig. 3 of the drawings. The shaft 110 carries a gear 111 that meshes with a gear 116 on the driven shaft 114 of the governor gear set, the shaft 114 being mounted in bearings 112113 and having its end 115 secured to a universal joint 117- which is. in turn connectedto the telescoping shaft that joins the universal joints 117121. The telescoping shaft, the

purpose of which will be later apparent, comprises an outer sleeve 118, and an inner rod 120 which has a slot 121* and through which the connecting pin 119 is passed, the pin 119 projecting through the hollow shaft or tube 118 and being secured in place by cotter pins or in any other suitable way. The rod section 120 of the shaft is c0nnected with the universal joint 121 that is mounted on the end of the driven shaft 123 of the drive wheel gear set. This shaft 123 is mounted in a bearing 124 of the cover 131 of the case 127 of the gear set and in a bearing 125 within the case 127, both bearings 124125 being bushed by a bearing metal 126, as shown. The case 127 has lugs 128 into which the cap screws 130 pass to secure the cover 131 in place.

129 designates pin and hole connections between the cover 131 and the case 127 to assist inmatching the parts when assembling the same. i

132 is a gear which is secured to the shaft 123 and meshes with a gear 133 on the driving shaft 134, the gear 133 being one element of a double gear, the other element 137 of which is united to the element 133 by a neck 138. The shaft 134 is mounted in bearings 135136 of the cover 131 and case 127 respectively, the bearings being suitably bushed with hearing metal bushings 126, as shown. The bearing 136 is extended as at 139 to receive the disk portion 157 of the supporting arm 158 to which the case 127 is riveted, as at 122 or rigidly secured in any other suitable manner.

The case 127 is rovided with bearin s- 140-144 in which the speedometer driving shaft 141 is located, the bearing 149 being bushed with a suitable bearing metal bushing 126.

The shaft 141 where it passes through the bearing 144 is provided with a collar 147 that carries a ball race 148 in which the hearing balls 146 are located, the ball race 148 being held in a recess in the cap 149, the cap being secured in place by cap screws 151.

The cap 149 has a threaded neck 150 to which the speedometer shaft casing (which may be of the usual type) 155 is secured.

Theshaft 141 has an extension 152 that is slotted at 153 to make connection with the speedometer shaft (not shown).

On a stud 177 carried by a clamp 178 that is secured to a part of the engine frame, is the bearing 156 of the arm 158 that supports the drive wheel 165 and the drive wheel. gear set, the arm 158 being formed with the disk 157, hereinbefore referred to.

161 designates an extension that is bored at 162 to receive an adjusting eye bolt 163 which is secured to the end of a spring 164, the other end of the spring 164 being fastened to a fixture 160, adjusting nuts 159 being provided whereby the tension of the spring may be regulated.

The friction wheel-165 may be formed in two sections; one of which 17 3 may serve as a cover for the other section.

The section 165 of the wheel is provided with inside lugs 166 having recesses to receive the ratchet pins 167 that have collars 168 and are pressed centrally by springs 169. The pins 167 having rounded ends 170 to seat in the notches 171 of the ratchet disk 17 which is keyed to the shaft 1341, the cover 173 is secured at 174- to the section 165 and both the section 165 and the cover 173 are bored to fit onto shaft 134, Washers 175 and lock nuts 176 being provided to hold the wheel on the shaft in practice.

In the operation of the invention when applied to train stopping apparatus, as hereinbefore described, when the train stopping mechanism operates to set the air brakes, if the speed of the train is below a predetermined minimum, the latch lug 97 will not be present in the slot 102 of the resetting rod 13 and therefore the engineer can reset the train stop valve by pulling the rod 13 in any convenient manner. If, however, the speed of the train is such as to be above the predetermined minimum, the latch 97 will be located within the notch 102 and thus prevent reciprocation of the rod 13. Power is transmitted to the governor spindle from the driver wheel of the locomotive through the medium of the driving wheel 165 which has rolling contact with the driver of the locomotive, as best shown in Fig. 1 of the drawings. The wheel 165 is held against the driver wheel by a yieldable support so that any unevenness in the roadbed may be compensated for without disconnecting the wheel 165 from the locomotive driver.

The provision of the telescoping shaft 118120 provides for any looseness in the engine structure or movements of the support 158 so that the governor mechanism may be rigidly mounted by the bracket 77 on the locomotive structure.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete construction, operation and advantages of my invention will be readily understood by those skilled in the art.
